She walked into my apartment like she was there for a class. "Teach me how to fuck," she said straight out, dropping her bag. "I want the dirty details, no bullshit. Show me everything."
I didn't waste time with small talk. I pulled her shirt over her head and told her to get on her knees. "First rule," I said, unzipping my jeans, "you suck cock like you mean it. Open wide and take it deep."
Her mouth wrapped around my dick right away, lips stretching as I pushed in. She gagged a little but kept going, tongue sliding under the shaft while I grabbed her hair and fucked her face slow at first. "That's it," I growled. "Spit on it, get it sloppy. Good girls make a mess." Saliva ran down her chin onto her tits. I pulled out and slapped my wet cock against her cheek. "Now lick the balls. Suck them one at a time."
She did exactly what I said, moaning around them, her hand stroking the shaft at the same time. My balls tightened fast, but I wasn't ready to come yet. I yanked her up, bent her over the couch, and ripped her jeans down. Her ass was round and firm. I spread her cheeks and spat on her asshole.

"Next lesson," I told her, rubbing the head of my cock against her pussy lips, "you get wet before you take it. Feel how soaked you are already?"
I slammed into her cunt in one thrust. She cried out, pushing back for more. "Fuck, you're tight," I said, pounding hard, skin slapping loud. "Clench around me. Milk that cock." Her pussy gripped me with every stroke. I reached around and rubbed her clit in fast circles. "This is how you make a girl come fast. Don't be gentle. Rub it like you want her screaming."
She came quick, legs shaking, juices dripping down my balls. I didn't stop. I flipped her onto her back on the floor, hooked her legs over my shoulders, and drove in deeper. "Look at me while I fuck you," I ordered. Her eyes locked on mine, mouth open, tits bouncing with every thrust. "Tell me how it feels."
"Harder," she gasped. "Fuck me harder."
I did, slamming so deep my balls slapped her ass. Sweat covered both of us. I pulled out, flipped her again, and pushed her face into the carpet while I took her from behind. "Doggy style," I said, gripping her hips. "Arch your back and spread your knees. Gives me full access to pound that hole." I reached under and fingered her clit again while I fucked her. She came a second time, screaming into the floor.
We moved to the bed. I had her ride me next. "How to sex story part three," I said as she lowered onto my cock. "You control the pace at first. Grind your clit against me, then bounce." She started slow, rolling her hips, then lifted up and slammed down. Her tits bounced in my face. I sucked one nipple hard while she fucked herself on me. "That's right. Use that dick."
When I was close, I threw her on her back and straddled her chest. "Open your mouth," I told her. I stroked fast and shot thick ropes across her tongue and lips. She swallowed what she could, the rest running down her chin. "Lesson complete," I said, catching my breath. "Now you know how to fuck."
She licked her lips and smiled. "Round two?"
